A kiss that adopts the jaw movements of Mars from "She's Gotta Have It". Specifically, the kiss entails a shimmying motion of one's jaw, while simultaneously slipping the tongue. It is highly recommended that one inform the recipient of the kiss that he/she will be performing this maneuver, so as not to alarm her/him and cause them to slap the sh*t out of him/her.
Greer: Yooooo. Guess what happened last night, bruh?
Jamie: 'Scuse me? Who the f**k are you, sir?

Jamie: Tell me more...
Greer: So what had happened was, right, like, I started kissing her and then started shimmying my jaw and sh*t, right, and then next thing I know,
she--
Jamie: ...Slapped the sh*t out of you?
Greer: Yeahhhhhh, how'd you know, bruh?
Jamie: Same sh*t happened to me last weekend.
Mars: Ahhhhhhh! Whack ass n****s.
